' (ci. sie-52') 13 claims.

'I'his invention relates to textile machines in which a strand is wound into a package ona bobbin or the like mounted frictionally on a rotatlng spindle, sa common example of such a machine being a ring spinning frame. More particularly, the invention is concerned with a novel attachment foruse on textile machines of the type referred to, which is operable to release the frictional grip of the full packages on their spindles and thus facilitate the work of the machine operator. i

In various textile machines, the bobbins, quills, cops, etc., are rotated by virictional engagement with the spindles on which they are mounted, and when full packages have been produced, these packages must be removed from the spindles in an operation known as doillng, an'd replaced by empty bobbins. Such domng is ordinarily performed manually, and, since a machine contains a large number of spindles, the doiiing operation is very tiring, particularly because considerable eiort on the part of the operator is required to release thel frictional engagement of the bobbins from the spindles.

'I'he present invention is directed to the provision .of an attachment for use on textile machines of the type referred to which enables the operator in a single operation to release the frictional.

lgrip lof all the yarn packages on the spindles on one side of the machine so that an important part of the labor involved in doillng is eliminated. 'I'he new attachment is of simple, inexpensive construction and it is easily operated. Also, it

does not interfere in any way with the normal use v of the machine to which it is applied.

The new attachment consists essentially ofa member which extends lengthwise of the'row of spindles in the textile machine and carries a plurality of lifter elements, one for each spindle. These elements are mounted on the member for movement relative thereto, and on movement of the member about its axis in one direction, the elements engage their respective yarn packages from beneath and release their frictional grip on the spindles. As the releasing operation .pro-

gresses, theelements move relative to the member, so that the forces applied to the packages through the elements may be properly directed to achieve the desired purpose.

For a better understanding of the invention,

reference may be made to the accompanying drawings, ln which F18.'1 is a view of the new attachment in front elevation with parts broken away;

Fig. 6 is an end view of a portion of the attachment seen from the line VI-VI of Fig. l;

Fig. 7 is a partial front elevation showing the attachment mounted on a spinning frame and with parts broken away;

Fig. 8 is a sectional view on line VIII-VIII of Fig. '7;v and l Fig. 9 is a view similar to Fig. 8 showing the parts in diiferent positions.

The attachment shown in the drawings is of a construction suitable'for useon a spinning frame having a bolster rail l0, in which are mounted the bearings Il for the spindles I2. Each spindle is provided with a whirl I3 by which it can be ro.

tated, and just above the whirl, the spindle has a conical section I4, which frictionally engages the inner surface of the lower end Ila of the bobbin IS mounted on a spindle.

-The new attachment comprises a member i8, preferably in the form of a pipe, which extends the entire length of the row of spindles and is supported for rotational movement in end supports I'l and intermediate supports Il. Each end support consists of a'bracket I! to which a tubular section 20 is attached in any suitable manner, as by .weldling, and each intermediate support comprises a bracket 2 I, similar to bracket I! and having a semi-cylindrical section 22 attached thereto, as by welding. An angle piece 22 attached to bracket 2| serves to holdthe pipe I6 in place in section 22. Collars 2l are mounted at the ends of the pipe to prevent endwise movement of the latter and, at one or both ends, a

handle 25 is attached to the pipe. In the inoperative position of the parts, the handleextends downwardly substantially vertically, so as not to interfere withl the movement of the operator along the front of the frame.

A plurality of bars 26 are mounted in alignment A on the pipe for rotational movement relative thereto and, for this purpose, each bar is attached to the pipe by hinges near its ends. Each hinge comprises a pin 21 extending through the pipe and having a portion outside the pipe lying parallel thereto and received within a tube 2l welded or otherwise secured to the bar. A coil spring 2l is mounted on the end of the pin projecting beyond tube 28,y and the ends of the spring bear against the tube and the bottom of the bar. The springs on the hinges supporting each bar, tend to move that bar relative to the pipe in a direction such that the top of the bar approaches the Figs. 2, 3, 4, and 5 are sectional views on the 55 vertical plane through the spindles. Each bar is may have an end 32 of reduced diameter fomed with a slot 33. A stepped opening is then drilled through bar 28, the end portions of the pin defining the slot are spread slightly, and the pin is forced into the opening, where it will be held in place by friction. With this arrangement, the pins can be readily removed for cleaning.

When the spinning frame is operating, the handle is in lowered position and the lifter pins 3| lie below the level of the lower ends of the bobbins on the spindles. When the bobbins have been illled and must be doed, the operator lowers the ring rail on the machine and then raises the handle 25 of the attachment. This causes the pipe i6 to be rotated and the upper ends of the lifter pins 3| are moved inwardly toward the spindles and upwardly. When the ends lof the lifter-pins engage the lower ends of the bins on the spindles has been broken, the handle 25 is released and the weight of the bars 26 and their pins causes reverse rotation of pipe i6 to restore the parts to their original condition. The

operator then completes the doiling and proceeds with the usual operations necessary to place the machine in condition for further operation.

While the new attachment has been illustrated a in the form suitable for use on a. ring spinning frame, it will be apparent that it may be applied without diillculty and with only minor modications to other textile machines, in which the bobbins are driven by frictional engagement with spindles. Accordingly, in the accompanying claims in which reference is made to yarn packages, it is to be understood that the use of that term vis not intended to limit the scope of those claims to an attachment for use in spinning frames only.
